Fetal Movements

Di
I'm 18 weeks pregnant and this is my second I lost 1st due to loss of fetal movement at 30 weeks, I'm always concerned about baby movement be coz of prior history. Any suggestions how keep track as I have started feeling movements but it's not regular and I just get concerned when I don't feel anything. Though it's too early to be anxious but do you feel regular kicks at so early stage?
